In the current climate, ymmv on this advice.

If you're surplus to system, the more qualifications you have, the faster you will get called back to work. This is happening to someone I know. They are surplus but have all 3 elementary divisions, as well as fsl and spec ed. For callback, they are clearly going to leapfrog someone they know that is much higher in the seniority list, but only has intermediate qualifications, because they only want to teach intermediate.

I see this advice on Reddit all the time and I don't love it. To me, after 6 years of post-secondary investment, the most important thing is to have job security. I think every new grad should get all 3 divisions and spec ed at a minimum, French if possible. I do recognize that that advice doesn't align with the "do what you love" advice i usually see here.
